Application June 14, 1948, Serial No. 32,856

10 Claims.

This invention relates in general to sheet metal roofing or siding.

In particular the invention is directed to, and it is an object toprovide a novel interlocking assembly for sheet metal roofing or siding;such assembly securing the cover sheets in unitary relation and withoutthe necessity of driving nails through the sheets.

While the invention is adapted for both roofing and siding. it will bedescribed as roofing for ease of description; it being understood,however, that the invention is not limited to this use.

Another object of the invention is to provide an interlocking assembly,for the purpose described, arranged so that the metal cover sheets ofroofing (or siding) may be applied readily in proper cooperativepositions, with adjacent sheets efiectively locked together inleak-proof and wind-resistant relation.

An additional object of the invention is to provide an interlockingassembly which is especially adapted for use in connection withcorrugated sheet metal roofing (or siding), although the invention maybe used with flat sheets if desired.

A further object of the invention is to provide an interlocking assemblywhich comprises a looking and retention strip beneath the lappedlongitudinal edge portions of adjacent cover sheets; there beinglongitudinally spaced upstanding eyes on the strip projecting upwardthrough matching slots in the under sheet, and locking hooks on theunder side of the upper sheet engaged in said eyes to complete theassembly. Such assembly is, of course, repeated at each of the lapped,longitudinal edge portions of adjacent sheets throughout the roof.

It is also an object of the invention to produce an interlockingassembly which is simple in structure, and economical to manufacture.

A further object of the invention is to provide a practical and reliableinterlocking assembly which will be exceedingly effective for thepurpose for which it is designed.

These objects are accomplished by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings:

Fig. 1 is a fragmentary plan view of adjacent corrugated cover sheets,and the corresponding locking and retention strip in separated relation;i. e. prior to assembly.

Fig. 2 is an enlarged transverse section of said parts as assembled.

Fig. 3 is a cross section on line 3-3 of Fig. 2.

Referring now more particularly to the characters of reference on thedrawings, the interlocking assembly is here shown as used in connectionwith corrugated sheet metal roofing. A pair of longitudinally extendingadjacent cover sheets, of corrugated sheet metal, are indicated at 1;one of said sheets being formed, in the bottom of the second channel 2inwardly from its longitudinal edge, with a plurality of evenly spacedtransverse slots 3.

A longitudinal, locking and retention strip 4 is disposed directlybeneath said channel 2, and is adapted to be fixed to the sheathing ofthe roof by nails (not shown), which are driven through a series ofholes 5 spaced lengthwise in said strip.

The strip, at points corresponding to the spacing of the slots 3 inchannel 2, has a plurality of eyes 6 struck outwardly therefrom, andeach of such eyes 6 includes a transverse slot 1.

The eyes 6 project outward through the transverse slots 3 in the bottomof the channel 2, and such eyes are of a height that the slots 1 of saideyes 6 are exposed above-the bottom of said channel. The adjacentlongitudinal edge portions of the cover sheets i are lapped, in themanner illustrated in Fig. 2, so that the channel 2 of the under coversheet receives the corresponding channel 8 of the upper cover sheet.

On the under side thereof, the channel 8 of the upper cover sheet isfitted, as by spot welding or the like, with a plurality of inwardlyprojecting square hooks 9 which all face in the same direction, andwhich hooks have exactly the same spacing as the slots 3 and eyes 55.Consequently, upon lap-ping of the longitudinal edge portions of thecover sheets i in the manner described, and with the eyes '6 projectingupwardly through the slots 3, the hooks 9 may be engaged in the slots 1of said eyes 6 upon longitudinal sliding motion of the upper cover sheetin a direction to accomplish this result. In other words, on a roof, theupper cover sheet i would be disposed with the square hooks 9 facingdownwardly, and with the hooks initially above the eyes 5. Then theupper sheet I would be shifted or slid downwardly to engage the hooks 9in the slots 1 of said eyes 6.

It will be recognized that a like interlocking assembly is employedbetween all of the adjacent longitudinal edges of the sheets throughoutthe roof, so that the latter is wholly locked together in properaline-ment and unitary relationship.

The interlocking is accomplished without nails being driven through thecover sheets I, which is very desirable. The only nailing which isrequired is to affix the locking and retention strips 4 to the sheathingor rafters.

While the interlocking assembly is quite simple in structure, andinexpensive to manufacture and use, it does provide for the efiectiveand reliable securing of sheet metal roofing (or sliding) in place.

From the foregoing description it will be readily seen that there hasbeen produced such a device as substantially fulfills the objects,'asset forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims.

Having thus described the invention, the following is claimed as new anduseful, and upon which Letters Patent are desired:

1. An interlocking assembly for sheet metal cover sheets on a supportwith adjacent edge portions of said sheets lapping, comprising a lookingand retention strip secured to the support lengthwise beneath saidlapping edge portions of the cover sheets, locking elements projectingoutward from the strip, the undermost lapped edge portion of the coversheets having openings through which said elements extend, and means onthe uppermost lapped edge portion of the cover sheets engaging saidoutwardly projecting elements in looking relation.
